Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567384, here are decompositions:

71 + 31567313 = 31567384
113 + 31567271 = 31567384
227 + 31567157 = 31567384
293 + 31567091 = 31567384
521 + 31566863 = 31567384
557 + 31566827 = 31567384
587 + 31566797 = 31567384
647 + 31566737 = 31567384

Showing the first eight; more decompositions exist.
